Gofu Save

My personal busybox built in Go

Project README


Gofu is a multibinary containing several utilities that I use everyday.

What's with the name?

A gofu, according to Wikipedia, is a type of household amulet or talisman, issued by a Shinto shrine, hung in the house for protection.

Alternatively, the name can also be read as "Go-fu".

This renders my shell prompt. Among other things, it identifies the current host by name and signature color (in the screenshot below, dark green for Krikkit); highlights path elements inside a Git repo (if any) and path elements that have been deleted; reports the current Git repo status; and reports the exit code of the previous command (if it failed). It also heavily saves space where possible, e.g. if the cwd starts with $GOPATH/src/, that is shortened to repo:. A prefix of $HOME/ is omitted entirely, as is my default user name.

This manages my Git repositories. Borrowing from the convention established by Go's GOPATH, the location of each local repository is defined by its remote URL. For example, this repo here will always be checked out at


The most common operation with rtree is to get a repository path:

$ rtree get https://github.com/majewsky/gofu

This will automatically clone the repo if it has not been cloned yet. Git URL aliases like these are supported. I use a shell function called cg that means cd to git repository and is based on rtree get:

$ pwd
$ cg gh:majewsky/gofu
$ pwd

When rtree get clones a new repo, it will look for existing repos with the same basename, and prompt the user about whether to treat this repo as a fork of some other repo:

$ cg gh:forkof/holo
Found possible fork candidates. What to do?
 [ ] add as remote to /x/src/aur.archlinux.org/holo
 [ ] add as remote to /x/src/github.com/holocm/holo
 [n] clone to /x/src/github.com/forkof/holo

There are a few other subcommands in rtree:

  • rtree drop <URL> deletes the local repo identified by the given remote URL (after asking for confirmation).
  • rtree repos lists the paths (below $GOPATH/src) of all local repos.
  • rtree remotes lists the remote URLs of all local repos.
  • rtree each <COMMAND> executes the given command in each repository. My most common usecase is rtree each git status --short.
  • rtree import <PATH> takes a path to a local Git repo, and moves it to the correct place below $GOPATH/src.

Finally, rtree index rebuilds the index file (~/.rtree/index.yaml) that all of these operations use to find repos and remotes. If a repo is checked out, but not yet indexed, the index entry will be added. If the repo for an index entry is missing, the user will be prompted about what to do:

$ rtree index
repository /x/src/github.com/Masterminds/sprig has been deleted
 [r] restore from https://github.com/Masterminds/sprig
 [d] delete from index
 [s] skip

One of the intended usecases is that stuff below $GOPATH/src does not need to be backed up. As long as the index file ~/.rtree/index.yaml is backed up, all repos can be restored in one step with yes r | rtree index.
